How it’s calculated
There are exactly 16 avoirdupois ounces in a pound. These are weight ounces; fluid ounces measure volume and need a density to convert.
1 oz = 0.0625 lb (exact) · 1 lb = 16 oz (exact)
lb = oz ÷ 16
- Divide the value in ounces by 16.
- Equivalently, multiply by 0.0625.
- 1 oz = 0.0625 lb · 1 lb = 16 oz
